How would you give the internal structure of the word 'unlawfulness'?
un - law - ful - ness
prefix - noun - suffix - suffix
law + ful > Adjective
un + law + ful > Adjective
un + law + ful + ness > Noun
Will that be correct? Should I split 'lawful' into 'law + ful' so there's four morphemes in the word or keep it as three morphemes? If 'lawful' is split, then is the -ful counted as a suffix or an infix?
